Hyaluronic Acid Concentration in Female Vocal Folds With Reinke's Edema.

Objective: The aim of the present study was to investigate hyaluronic acid (HA) concentrations in vocal folds among patients with Reinke's edema.

Study Design: Prospective and experimental study.

Setting: Single tertiary center.

Sulfated glycosaminoglycans in human vocal fold lamina propria.

Introduction: The distribution, concentration and function of glycosaminoglycans in the various vocal fold tissues are still unclear.

Objective: To evaluate the distribution and concentration of sulfated glycosaminoglycans in different layers of the human vocal fold according to gender and age.

Methods: We used 11 vocal folds obtained from cadavers (7 men and 4 women) with no laryngeal lesion, less than 12h after death, and aged between 35 and 98 years.

GLYCOSAMINOGLYCANS AND PROTEOGLYCANS IN PALMAR FASCIA OF PATIENTS WITH DUPUYTREN.

Objective: : To evaluate and compare the behavior of glycosaminoglycans (GAGs) in Dupuytren disease (DD).

Methods: : This is an experimental study with 23 patients diagnosed with DD. Tissue collected through fasciectomy with incision type Brunner or McCash were evaluated by electrophoresis for identification of GAGs.

Concentration of hyaluronic acid in human vocal folds in young and old subjects.

Objective: To compare and evaluate concentrations of hyaluronic acid (HA) in normal vocal folds of both young and elderly people of both sexes.

Study Design: Experimental study.

Setting: The research was carried out at the ENT, Head and Neck Surgery Department and the Pharmacology Institute of São Paulo Federal University.

Analysis of glycosaminoglycans in the parametrium and vaginal apex of women with and without uterine prolapse.

Background: Pelvic organ prolapse (POP) is a downward descent of pelvic organs that results in protrusions of the vagina, the uterus, or both. The cause of this disorder is likely to be multifactorial, attributable to a combination of risk factors, especially connective tissue disorders. Our objective was to characterize and quantify a component of the extracellular matrix (ECM)-sulfated glycosaminoglycan (GAG)-in the parametrium and vaginal apex of women with and without uterine prolapse.

[Evaluation of glycosaminoglycans of periurethral tissue in patients with and without pelvic organ prolapse].

Objective: To characterize and quantify periurethral tissue sulphated glycosaminoglycans (GAGs) in women with and without pelvic organ prolapse.

Study Design: Periurethral tissue was obtained from 35 women who underwent surgery for pelvic organ prolapse, for stress urinary incontinence, or for other gynecological benign conditions. Patients were submitted to a clinical history, physical and urodynamic examination and were divided in two groups according to genital prolapse.
